Register 0x1100: CSPI Clock Synthesis Configuration
The Clock Synthesizer and 4 PISO block performs clock synthesis and serialization of the
transmit serial interface stream.
ROOLI:
Reserved:
The ROOLI bit is the reference out of lock interrupt status bit for the CSU. The ROOLI is
set high when the ROOLV register changes state, indicating that either the CSU is within
488ppm of the reference clock REFCLK or is out of lock. ROOLI is cleared when this
register is read. If the corresponding ROOLE interrupt enable is high, the INTB is also
asserted when the enabled ROOLI asserted.
These registers must be programmed with logic zero for proper operation.
